From f4512e6579ddaa9b1f8ab1d5659131243ffc421f Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 20 Oct 2010 11:47:09 +1000 Subject: [PATCH] drm/nv50: create graph and crypt contexts on demand This really needs cleaning up somehow, and probably investigate what's needed to do this on earlier generations. NVIDIA do something similar there too.
